Food Allergies

Millions of Americans experience food allergies every year. These allergies can range from mild to severe and life-threatening. They occur when your body has an abnormal immune response to a certain food.

There are eight
main food groups
that cause 90
percent of all
food allergies.

They are eggs, milk, peanuts, tree nuts, fish, shellfish, wheat and soy.

Not all reactions to food are allergies. Some reactions are actually a food intolerance. An intolerance occurs when your body has a difficult time digesting food. Even though food intolerance and allergies can cause some of the same symptoms, they are different reactions and need to be treated differently.

If the symptoms are severe and anaphylactic, call 911 or visit the emergency room immediately as this reaction is life-threatening if left untreated.

Eosinophilic Esophagitis Food Allergen Testing

Food Allergies fayetteville arkansasIf you have been diagnosed with Eosinophilic Esophagitis (EoE), your GI doctor may refer you to be tested for food allergy. Allergy testing can help identify which foods may be triggering EoE symptoms. These foods can then be removed from the diet. There are two main ways we detect food allergies in EoE.

  • Skin prick testing. This test involves ‘scratching’ small amounts of a food into the skin and observing the reaction. This helps to determine if there is an immediate response to the food.
  • Patch testing- This test involves placing small amounts of food extract/flours into tiny cups, which are then taped to the back. The patches are removed after 48 hours and read at 72 hours. The prolonged exposure of the skin to the extracts helps to determine if there is a delayed response to a food.

Allergy testing will involve both of these tests to identify food allergen triggers. With the help of this testing, EoE can be managed and most patients have an excellent response to treatment.
